Peripheral Functions
JTAG Port Connections
Nexus OCD AUX Port Connections
Each GPIO line can be assigned to one of several peripheral functions. The following table
describes how the various peripheral functions are selected. The last listed function has priority
in case multiple functions are enabled.
Table 3-2.
If the JTAG is enabled, the JTAG will take control over a number of pins, irrespective of the I/O
Controller configuration.
Table 3-3.
If the OCD trace system is enabled, the trace system will take control over a number of pins,
respectively of the I/O Controller configuration. Two different OCD trace pin mappings are possi-
ble, depending on the configuration of the OCD AXS register. For details, see the AVR32 UC
Technical Reference Manual.
